Hi,

Sokets are registered at runtime using the function:
void add_olsr_socket(int fd, void(*pf)(int))
in socket_parser.c
The OLSR sockets(UDP/698) are registered one pr. interface. Check out 
the linux interface config in src/linux/ifnet.c to see where the sockets 
are created and added to the parser.

 From ifnet.h:

/* Network interface configuration interface.
  * Platform independent - the implementations
  * reside in OS/ifnet.c(e.g. linux/ifnet.c)
  */

I don't think that needs any further explanation ;-)
(you might have an earlier version where that comment is not added)
